Sorry I don't understand you. If you want to run them in parallel you cannot wait for one to succeed before launching the next...

You could do this in test.sh

I don't know what you have in test1.sh but if it is a simple command to shutdown some process, you could call the...

Thank you both for jumping on this so quickly :D

This is perfect for what I need:

awk -F'[$][{]' '{for(i=2; i<=NF; i++){sub(/[^_A-Z0-9].*/,x,$i); print NR, $i}}'

Hi All

I think I might have bitten off more than I can chew here and I'm hoping some of you guys with advanced pattern matching skills can help me.

What I want to do is index the occurrence of...

Thanks very much guys

That's the kind of stuff I have been looking for.

I'll certainly play around with the code posted and I wasn't aware of the select command, I assumed it was something low...

Hi Mig

I don't get your comments about the while loop.

The example I posted is reading from a file that contains messages from remote servers.

Thanks for the -x tip but I was looking for...

Thanks Corona

I'm running it under strace now and of course it has stopped failing....

Yes, the reason I didn't post any code was because it is a distributed application with multiple libraries...

I was more interested in finding some online tutorials on how to trace into a hanging job effectively...

But as you ask:

The script is running jobs over ssh on remote servers.

A file based...

Can anyone recommend any good guides on how to investigate what a hanging process is doing?

In fact I would be interested in any online guides that would improve my forensic skills on the Linux...

Hi Robin

Thanks but I am hoping to perhaps calculate the size in bytes and then create a file in a directory about that size... Perhaps using something like dd?

I wouldn't want the automation...

Well that is exactly what I am trying to achieve. Stress the system and look for problems.

But to your specific question, no the logging should not get out of hand. It should just log that it has...

Nothing sinister... Like I said, this is for some automated resilience testing. I need to prove that a service can cope when it has insufficient disk space available.

The service is...

Hi

I'm doing some resilience testing and need to write a script to consume all of the available disk space on a partition and then to free it up again.

This would need to be -

Dynamic,...

Thanks :)

That should give me something to Google....

In addition to my thanks - thanks...

Hi All

I am resilience testing an application that is spread across multiple servers.

One thing I will need to do soon is throttle the network traffic for specific interfaces within the test...
